Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a cooling component for precision injection molded parts. Background Technique

[0002] The cooling of precision injection molded parts after demolding is a key process, which directly affects the quality and performance of injection molded parts. The choice of cooling method should be determined according to specific product and process requirements. The length of the cooling time has an important impact on the cooling effect and production cycle of injection molded parts. Too short cooling time may cause the plastic to not be fully cooled and solidified, thus affecting the dimensional accuracy and mechanical properties of the product. And too long cooling time will prolong the production cycle and reduce production efficiency.

[0003] The existing cooling of precision injection molded parts is achieved by setting multiple groups of nozzles. However, some precision injection molded parts produced may have relatively fragile plastic structures. After being impacted by the cooling water, the structure of the injection molded parts may shift or even break and be damaged in severe cases, thus reducing the qualified rate of injection molded parts during the cooling process. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cooling component for precision injection molded parts to solve the problem that the existing cooling of precision injection molded parts is achieved by setting multiple groups of nozzles. However, some precision injection molded parts produced may have relatively fragile plastic structures. After being impacted by the cooling water, the structure of the injection molded parts may shift or even break and be damaged in severe cases, thus reducing the qualified rate of injection molded parts during the cooling process as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A cooling component for precision injection molded parts includes a sinking mechanism, and a circulating drainage mechanism is fixedly arranged outside the sinking mechanism;

[0007] The sinking mechanism includes a placement plate, four sliding columns are symmetrically and slidably inserted into the placement plate with respect to its vertical center plane. A splicing cage body is fixedly connected between two adjacent sliding columns. An extrusion spring is fixedly connected to the end of the sliding column. An inclined slider is fixedly connected to the end of the sliding column. The outside of the inclined slider is slidably abutted against a bent slide rail. The end of the bent slide rail is fixedly connected to a cooling box.

[0008] Furthermore, one end of a connecting rope is fixedly connected to the bottom of the placement plate. A positioning wheel rotatably connected to the cooling box is wound around the connecting rope. The end of the connecting rope is fixedly connected to a winding wheel. The output end of a servo motor is fixedly connected to the central position of the winding wheel. A positioning seat is rotatably connected to one side of the winding wheel.

[0009] Furthermore, sliding seats are fixedly connected to the central positions of the opposite side walls of the placement plate. A limiting column fixedly connected to the inner wall of the cooling box is slidably sleeved in each of the two sliding seats, and a return spring fixedly connecting the limiting column and the sliding seat.

[0010] Furthermore, a plurality of hollow holes are equidistantly formed in the splicing cage body.

[0011] Furthermore, the circulating drainage mechanism includes a cavity shell. Two drainage columns communicating with the inside thereof are symmetrically and fixedly connected to the opposite inner walls of the two cavity shells. A three-way pipe communicating with the inside thereof is fixedly connected between the two cavity shells. The end of the three-way pipe is fixedly connected to the output end of a first circulation pump. The input end of the first circulation pump is fixedly connected to a water storage tank, and a coolant is filled in the water storage tank.

[0012] Furthermore, a water outlet pipe communicating with the inside thereof is fixedly connected to the bottom end of the outer wall of the cooling box. The end of the water outlet pipe is fixedly connected to the input end of a second circulation pump. The output end of the second circulation pump communicates with the water storage tank, and a plurality of heat dissipation fins are equidistantly and fixedly connected to the outer wall of the water storage tank.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. After multiple precision injection molded parts are taken out of the mold, they are placed on the placement plate. Then, the output end of the servo motor drives the winding wheel to rotate, so that the winding wheel can wind the connecting rope. Then, the end of the connecting rope drives the placement plate to descend, thereby driving the inclined slider to slide in the bending slide rail. Therefore, under the limit of the inclined surface of the bending slide rail, the sliding column can be gradually pushed to slide and be received into the placement plate, so as to drive the two splicing cage bodies to merge together. By continuously driving the placement plate to descend, the splicing cage body and the precision injection molded parts can be driven to gradually sink into the coolant in the cooling box. Through the immersion method, the injection molded parts can be effectively cooled. The merged splicing cage bodies can block the injection molded parts to prevent the injection molded parts from floating up, so that the injection molded parts will not be damaged during the cooling process.

[0015] 2. The high-temperature coolant that has processed the injection molded parts in the water storage tank can be discharged through the water outlet pipe, and it is pumped into the water storage tank by the second circulation pump. At the same time, the low-temperature coolant in the water storage tank is pumped into the three-way pipe by the first circulation pump. Then, the low-temperature coolant can be discharged into the cooling box through the drainage column. The heat dissipation fins can accelerate the heat dissipation of the coolant in the water storage tank. By circulating and using the coolant in the cooling box, the cooling effect of the equipment can be maintained. Description of the Drawings

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 5 , in the embodiments of the present utility model, a precision injection molding part cooling assembly includes a sinking mechanism 100, and a circulating drainage mechanism 200 is fixedly arranged outside the sinking mechanism 100;

[0024] The sinking mechanism 100 includes a placement plate 101. Four sliding columns 103 are symmetrically and slidably inserted into the placement plate 101 with respect to its vertical center plane. A splicing cage body 104 is fixedly connected between two adjacent sliding columns 103. An extrusion spring 107 is fixedly connected to the end of the sliding column 103. An inclined slider 106 is fixedly connected to the end of the sliding column 103. The outer part of the inclined slider 106 is slidably abutted against a bent slide rail 108. A cooling box 109 is fixedly connected to the end of the bent slide rail 108. One end of a connecting rope 112 is fixedly connected to the bottom of the placement plate 101. A positioning wheel 113 rotatably connected to the cooling box 109 is wound around the connecting rope 112. The end of the connecting rope 112 is fixedly connected to a winding wheel 114. The output end of a servo motor 116 is fixedly connected to the center position of the winding wheel 114. A positioning seat 115 is rotatably connected to one side of the winding wheel 114. A plurality of hollow holes 105 are equidistantly arranged on the splicing cage body 104.

[0025] Specifically, by placing a plurality of precision injection molded parts after demolding on the placement plate 101, and then driving the winding wheel 114 to rotate through the output end of the servo motor 116, the winding wheel 114 can wind the connecting rope 112. Then, the end of the connecting rope 112 drives the placement plate 101 to descend, thereby driving the inclined slider 106 to slide in the bent slide rail 108. Therefore, under the limit of the inclined plane of the bent slide rail 108, the sliding column 103 can be gradually pushed to slide and be received into the placement plate 101, thereby driving the two splicing cage bodies 104 to merge together. By continuously driving the placement plate 101 to descend, the splicing cage body 104 and the precision injection molded parts can be driven to gradually sink into the coolant in the cooling box 109. Through the immersion method, the injection molded parts can be effectively cooled. The merged splicing cage body 104 can block the injection molded parts to prevent the injection molded parts from floating up, so that the injection molded parts will not be damaged during the cooling process.

[0026] Embodiment 1

[0027] As Figure 3 shown, in this embodiment, sliding seats 102 are fixedly connected to the center positions of the opposite side walls of the placement plate 101. A limiting column 110 fixedly connected to the inner wall of the cooling box 109 is slidably sleeved in both sliding seats 102. A return spring 111 fixedly connecting the limiting column 110 and the sliding seat 102.

[0028] In this embodiment, when the winding wheel 114 releases the connecting rope 112, the placement plate 101 will gradually rise under the pushing and squeezing of the return spring 111. At the same time, the inclined slider 106 will slide along the inner wall of the bent slide rail 108, and then the sliding column 103 will pop out under the action of the extrusion spring 107, thereby driving the splicing cage bodies 104 on both sides to separate, facilitating the removal of the cooled injection molded parts and the placement of new injection molded parts to be cooled.

[0029] Example Two

[0030] As Figure 5 shown, in this embodiment, the circulating drainage mechanism 200 includes a cavity shell 201. On the opposite inner walls of the two cavity shells 201, two drainage columns 202 communicating with their interiors are symmetrically and fixedly connected. A three-way pipe 203 communicating with its interior is fixedly connected between the two cavity shells 201. The end of the three-way pipe 203 is fixedly connected to the output end of a first circulation pump 204. The input end of the first circulation pump 204 is fixedly connected to a water storage tank 205, and the interior of the water storage tank 205 is filled with a coolant. The bottom end of the outer wall of the cooling box 109 is fixedly connected to a water outlet pipe 208 communicating with its interior. The end of the water outlet pipe 208 is fixedly connected to the input end of a second circulation pump 207, and the output end of the second circulation pump 207 communicates with the water storage tank 205. A plurality of heat dissipation fins 206 are equidistantly and fixedly connected to the outer wall of the water storage tank 205.

[0031] During specific implementation, the high-temperature coolant that has finished processing the injection molded part in the water storage tank 205 can be discharged through the water outlet pipe 208, pumped into the water storage tank 205 by the second circulation pump 207. At the same time, the low-temperature coolant in the water storage tank 205 is pumped into the three-way pipe 203 by the first circulation pump 204. Then, the low-temperature coolant can be discharged into the cooling box 109 through the drainage columns 202. The heat dissipation fins 206 can accelerate the heat dissipation of the coolant in the water storage tank 205. By circulating and using the coolant in the cooling box 109, the cooling effect of the equipment can be maintained.
